WHO AM I? I am your constant companion, I am your greatest helper or heaviest burden. I will push you onward or drag you down to failure, I am completely at your command. Half the things you do, you might just as well turn over to me, I will do them quickly and correctly. I am easily managed – you must merely be firm with me. Show me exactly how you want something done and after a few lessons, I will do it automatically. I am the servant of all great people; and alas, of all failures as well. Those who are great, I have made great, those who are failures, I have made failures. I am not a machine, though I work with all the precision of a machine plus the intelligence of a human. You may run me for a profit or run me for ruin, it makes no difference to me. Take me, train me, be firm with me and I will place the world at your feet, be easy with me and I WILL DESTROY YOU!
